Question

1. Given the vertical curve information below, compute stations and elevations at the PVI, EVC. and full stations, Also determine the station and elevation of the summit.

Solution

xxx = xxx -x/x xx = xxx - xx/x xxx = 23 +xx/x

=30

xxx = xxx + x/x

= xx + xx/x

= xx

Therefore xxx xxxxxxxxx xxx

(elevation xx station24 = xxx+x.x = 319.42)

xx = xxx.xx xx = 319.42

xx = xxx.xx xx = 326.42

xx = xxx.xx xx = 333.42

xx = xxx.xx xx = 340.42

xxxxxxxxx at xxxxxxxxx = xxx.xx-x.xx = xxx.xx

31 = xxx.xx xx = xxx.xx

33 = xxx.xx xx = xxx.xx

35 = xxx.xx xx = xxx.xx

37 = xxx.xx xxxxxxxxx at xxx = xxx.xx xxxxxxxxx xx C = (315.42+331.67)/2

= xxx.xx xxxxxxxxx at x = (xxx.xx+xxx.xx)/x = xxx.xx

offset = 332.10 - xxx.xx = 8.31

xxxxxxx offset xx xx = (1002/7002) (x.xx) = x.xx xxxxxxx xxxxxx at xx = (xxxx/xxxx)(x.xx) = x.xx

26 = (1002/5002)(8.31) = x.xx xx = (xxxx/xxxx)(x.xx) = x.xx xx = (1002/3002)/(8.31) = 0.92

xx = (xxxx/xxxx)/(x.xx) = x.xx

Substract xxxxxxx xxxxxxx xxxx elevation xx get xxxxxxxxxx xx xxxxx

after xxxxxxxxxxx the xxxxxxx xxxxxxx xxx elevation xxx

23 = xxx.xx xx = xxx.xx

25 = xxx.xx xx = xxx.xx

27 = xxx.xx xx = xxx.x

29 = xxx.xx xx = xxx.xx

31 = xxx.xx xx = xxx

33 = xxx.xx xx = xxx.xx

35 = xxx.xx xx = xxx.xx

37 = xxx.xx
